SPECIFICATION forming part of Letters Patent No. 733,532, dated July 14, 1903.

Application iiled January 8, 1903. Serial No. 138,249. (No model.)

T0 ail whom it may concern,.-

Be it known that I, SAMUEL R. BAILEY, a citizen of the United States, and a resident of Amesbury, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Axle-Nuts, of which the following is a specification.

This invention relates to improvements on the patent granted to me for adjustable axlenuts April 18, 1899, No. 623,124, and is especially designed for carriage-axles, either with or Without ball-bearings, for the purpose of setting up from time to time and adjusting the position of the axle-nut relative to the end of the wheel-hub, its washer, or cone-bearing and holding said nut securely in its adjusted position without the employment of check-nuts, as will hereinafter be more fully shown and described, reference being had to the accompanying drawings, wherein- Figure 1 is a side elevation of the invention. Fig. 2 is a longitudinal section on the line 2 2 shown in Fig. l. Fig. 3 is a crosssection on the line 3 3 shown in Fig. 2. Fig. 4 is a detail side elevation of the adjustable axle-nut, sho-wing it detached from the axle. Fig. 5 is a cross-section similar to Fig. 3, showing the interior bore of the axle grooved longitudinally for additionally retaining the axlenut in its adjusted position. Fig. 6 is a longitudinal section of a modified form of the frictionally-adjustable axle-nut device, and Fig. 7 is a cross-section on the line 7 7 shown in Fig. 6.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, A represents the outer end portion of a carriage-axle, and B represents the washer or cone-bearing longitudinally adjustable on said axle end, as usual.

Centrally within the outer end of the axle A is made a cylindrical bore or recess A', as shown in Figs. 2, 3, 6, and 7, which is made of an equal diameter throughout its entire length, as shown in the drawings. The outer end of said longitudinal recess is provided with an internal female screw-thread A, as shown in Figs. 2 and 6.

C represents the head of the axle-nut, which may be adjusted by means of a suitable span ner or wrench, as may be most prac tical and convenient. Integral with the head (l is made a screw-threaded shank C, which is adjustable within the female screw-thread A, as shown. Preferably integral with the inner end of the screw-threaded shank C is made a friction-retaining device, which may be madein the form of yielding bifurcated prongs C C" (shown in Figs. 2, 3, and 4) 0r asasingle curved yielding tongue C5. (Shown in Figs. 6 and 7.) .l It will thus be noticed that the axle-nut is held frictionally in position within the axle during and after being adjusted therein by the frictional engagement of the expansive prong or prongsv with the interior surface of the cylindrical recess A', as shown in the drawings.

In my aforesaid patent the inner end of the recess A is shown as being tapered for the compression ofthe yielding prong or prongs on the axle-nut; but in practice I have found it desirable to hold the axle-nut frictionally secured within the recess of the axle with equal pressure throughout the whole range of its longitudinal adjustment, and therefore I have made such recess A of equal diameter throughout its entire length, so as to cause the expansive prong or prongs on the axlenut to be held frictionally with equal pressure against the interior cylindrical bore A throughout the length of adjustment of the axle-nut.

In devices of this kind it may be desirable to still further hold the expansive prong or prongs on the axle-nut secured within the bore of the axle after adjustment, and for such purpose I may to advantage provide the interior bore of the axle with a series of longitudinal fluted recesses or undulations A3 A3, (shown in Fig. 5,) adapted to receive the expansive ends of the axle-nut prongs, so as to provide a positive lock between the axle-nut and the axle after said axle-nut has been adjusted.

By the construction as hereinabove shown and described the axle-nut may be readily adjusted, thus eftectually preventing it from working loose by the jarring of the vehicle.

By this arrangement I dispense entirely with the ordinary set-nut usually employed in devices of this kind, and by the arrange-y ment as shown and described the axle-nut ICO can be most easily and quickly adjusted simply by turning a single piece-namely, the head of the device.

Having thus fully described the nature, construction, and operation of my invention, I Wish to secure by Letters Patent and claim-- l. The herein described adjustable axlenut device, consisting in combination With an axle having a cylindrical recess of even size throughout its length, and screw-threaded at its outer end, a screw-threaded shank adjustable Within the screw-threaded portion of the .axle and having expansive yielding prong or 'prongs adapted to be held frictionally against nut device, consisting in combination with an axle, having a longitudinal recess of even size throughout its length, screw-threaded at its outer end, and having longitudinal grooves or undulations, a screw-threaded shank adjustable Within the screw-threaded portion of the axle and having expansive yielding prong or prongs adapted to interlock with the longitudinal grooves on the interior ofthe recess in the axle substantially as and for the pur-v pose set forth.

In testimony whereof l have aftixed my signature in presence oi?l two Witnesses.

SAMUEL R. BAILEY.
